The cost of buying a home in Castellar del Vallès

The ministry publishes no appraisal average for this municipality, so the market figures below stop at the notarial sales count. Castellar del Vallès is a town rather than a city, which in Barcelona usually means one estate agency network knows most of the stock. Almost nothing here is a second home: 10,98 % of dwellings are not somebody's main residence.

The bill that lands on the day of the deed

The Catalonia transfer tax applies to resale purchases in Castellar del Vallès; a new build is charged VAT and stamp duty instead. Catalonia charges transfer tax on a progressive scale rather than a single rate, starting at 10 % and rising through bands as the value goes up; the table below applies the scale bracket by bracket.

The yearly bill, which is not small here

At 84.322 € per dwelling, the Castellar del Vallès cadastral base is high enough that the rate matters.

The 0,83 % urban IBI rate in Castellar del Vallès is high by Spanish standards.

The rural rate of 0,83 % is unusually close to the urban one.

180.000 € of cadastral value at 0,83 % is 1.494 € a year, but the base is dated and a revision would change it sharply.

The cadastral value in this example is a round illustrative figure, not the cadastral value of any particular property here. Ask for the last IBI receipt: it states the real one.

The cadastral values are dated

The Castellar del Vallès register dates from 2002; a future revision could move the yearly bill significantly even if the rate never changes.

Building work is taxed at 3,79 %, near the top of what town halls may charge.

What the market looks like

The ministry does not publish this figure for Castellar del Vallès, so it is stated here as not available rather than estimated.

A stock of homes people actually live in

Only 10,98 % of Castellar del Vallès dwellings are not somebody's main home, so the market is driven by people who live here.

10.052 dwellings were counted at the census.

Almost the whole register is housing: 10.063 residential units out of 15.628 urban ones.
